Have Submachineguns become Obsolete? Enter the .300 Whisper.

The answer to the special operations community’s prayers may exist in the .300 Whisper cartridge by SSK Industries.

Invented by J.D. Jones, the .300 Whisper utilizes a very heavy .30 caliber rifle round combined with a shortened case. According to Mr. Jones, "the 300 WHISPER was designed for the purpose of firing extremely heavy, accurate, ballistically efficient bullets at sub-sonic velocities and is now the state of the art long range cartridge in suppressed weapons. It delivers more energy more accurately than any existing sub-sonic round at 200 yards {and a lot further} (except other WHISPERS). In addition, it has interesting sonic capabilities – possessing greater versatility than any other cartridge capable of performing in these vastly differing arenas."
